Iranians are attending mourning ceremonies in their millions across the country to mark Ashura Day, the day in history that witnessed the martyrdom of Shia Islam’s third Imam.

The faithful have converged on the streets and in mosques with heavy hearts to honor Ashura, the 10th day of the first month of the Islamic lunar calendar Muharram, which is the climax of the mourning processions.

During the ceremonies, eulogies are recited and sermons delivered in memory of Imam Hussein and his 72 companions.
